EMC Ionix ControlCenter 6.1: Taking Control of Your Datacenter
Monitoring Your Datacenter
Automating the resolution to an Oracle tablespace space
shortage
In this example, a tablespace that belongs to the Sales database exceeds a threshold
of 95 percent occupancy. The database administrator (DBA) identifies the problem by
noticing an alert icon on the DBA folder in the tree.
During the configuration phase, the DBA configured an autofix that would
automatically trigger a script he had previously written to expand a tablespace. He
attached the autofix to the tablespace alert.
Following the alert trail
The DBA first identifies the tablespace problem when a downward-pointing arrow
appears on the DBA folder in the tree (Figure 69).
Figure 69 An alert in the DBA folder
During the configuration phase, the Operations Manager and DBA created the DBA
folder in the tree to contain the hosts and databases for which the DBA is responsible.
To find out which host or database has the problem, the DBA:
